Let's solve each equation step by step:

First, let's simplify both sides of the equation:

1600 - 65x = 1215 + 45x
1600 - 1215 = 45x + 65x
385 = 110x

Now, divide by 110 to solve for x:

x = 385 / 110
x = 3.5

So, the solution to the first equation is x = 3.5

First, distribute the 5 to the terms inside the parentheses:

4x + 15 - 10x = 5 - 11x

Combine like terms on both sides:

4x - 10x + 15 = 5 - 11x
-6x + 15 = 5 - 11x

Now, add 11x to both sides and subtract 15:

-6x + 11x + 15 = 5 - 11x + 11x
5x + 15 = 5

Finally, subtract 15 from both sides to solve for x:

5x = 5 - 15
5x = -10
x = -10 / 5
x = -2

So, the solution to the second equation is x = -2

Therefore, the solution set for both equations is x = 3.5 and x = -2.
